What is angles?
An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are on the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.
The angles are corresponding angles so they are equal if m is parallel to n

You want the equation of AD perpendicular to BC, where the point coordinates are A(4, 6), B(1, 2), C(6, 2).
Horizontal lineWe notice the y-coordinates of point B and C are the same, indicating the line is horizontal. Its equation is y = 2.
Perpendicular lineThe line perpendicular to the horizontal line y = 2 will be a vertical line. Its equation will be of the form ...

What is the arithmetic mean of the following numbers 8 1 2 6 1 4?
The mean for a given set of observations is 3.67.
What is mean?The mean is the average of a set of variables in mathematics and statistics. The mean may be calculated in a variety of methods, including the simple arithmetic mean (add the numbers and divide the total by the number of observations), geometric mean, and harmonic mean. A data set's mean (average) is calculated by summing all of the numbers in the set and then dividing by the number of values in the set. When a data collection is arranged from least to largest, the median is the midway value. The mode is the number that appears the most frequently in a data collection.

What is the factored form of 3x² 14x 8?
The factored form of 3x² + 14x + 8 is (3x + 4)(x + 2).
What is factor?Factor is a number that can be divided evenly into another number. Factors are used in mathematics to simplify equations, calculate percentages, and solve problems. Factors can also be used to identify the greatest common factor (GCF) between two or more numbers. Factors can also be used to find the least common multiple (LCM) of two or more numbers.
This is the product of the two binomials (3x + 4) and (x + 2),which are the factors of the equation.
The process of factoring an equation involves breaking it down into its component parts,
which in this case are 3x² + 14x + 8. The factors of this equation are determined by first finding the greatest common factor (GCF) of the terms, which in this case is 3x + 4.
Then, the GCF is divided by each of the terms to determine the other factor. For example, 3x² / 3x + 4 =x + 2.
When the two factors are multiplied together, the result is the original equation.

What will be the end behavior of the graph if the highest degree of the function is odd and its leading coefficient is positive?
The end behavior of the graph will be that it increases without bound as x approaches positive infinity, and decreases without bound as x approaches negative infinity.
The end behavior of a graph is a description of how the graph behaves as the x-values approach either positive or negative infinity. If the highest degree of the function is odd and the leading coefficient is positive, then the end behavior will be that the graph increases without bound as x approaches positive infinity and decreases without bound as x approaches negative infinity. This can be explained by examining the degree of the function. Since the degree is odd, the highest degree of the function must be an odd power, such as x^3. When x is positive and increasing without bound, the value of the function will also be increasing without bound, since the exponent is positive. Similarly, when x is negative and decreasing without bound, the value of the function will also be decreasing without bound, since the exponent is negative.

a) The length of AB is given as follows: 14.387.
b) The measure of angle BAC is given as follows: 78.4º.
How to obtain the length of AB?The length of AB, from the sketch of the triangle given by the image at the end of the answer, is obtained using the law of cosines, as follows:
x² = a² + b² - 2abcos(C).
The parameters from the triangle are given as follows:
a = 8, b = 15, C = 70º.
Hence the length of AB is given as follows:
x² = 8² + 15² - 2 x 8 x 15 x cos(70º)

x = 14.387.
How to obtain te measure of angle BAC?
The measure of angle BAC is obtained using the law of sines, as follows:
sin(x)/15 = sin(70º)/14.387
sin(x) = 15 x sin(70º)/14.387

Define regression.A statistical measure that identifies the link or co-relationship between two variables. explains the relationship between an independent variable and a dependent variable. The scatter of data points around the regression line plays a key role in estimating the slope's uncertainty in regression analysis. The data points are more dispersed and the estimation of the slope is less accurate when there is a lot of scatter. Because the estimation of the slope is based on the data points, it is less accurate when there is greater scatter in the data points.
Given
When I. there is a lot of scatter around the regression line, b1 is higher.
I am higher. The uncertainty surrounding the slope estimate, b1, increases with the amount of scatter around the regression line. The calculated slope is less dependable when there is a lot of scatter than when there is very little scatter.
When there is a large amount of scatter around the regression line, the uncertainty associated with the slope estimate, b1, is higher. This is due to the fact that the estimate of the slope depends on the data points, and when there is a lot of scatter, the data points are more dispersed, making the estimate of the slope less accurate.

what is the slope between (-9,3) and (-1,1)
Answer:
m = -1/4
Step-by-step explanation:
The slope is rise/run or (y2 - y1) / (x2 - x1)
We see the y decrease by 2 and the x increase by 8, so the slope is
-2/8 = -1/4
Answer:
Slope = -1/4
Step-by-step explanation:
Now we have to,
→ find the needed slope.
Formula we use,
→ Slope(m) = (y2 - y1)/(x2 - x1)
Then the slope will be,
→ m = (y2 - y1)/(x2 - x1)
→ m = (1 - 3)/(-1 -(-9))
→ m = -2/(-1 + 9)
→ m = -2/8
→ [ m = -1/4 ]
Hence, the slope is -1/4.
What is 5x 2y 3 in slope intercept form?
The line's equation is written as y = (-5/2)x + (3/2) in slope-intercept form.
According to the slope-intercept form, in the equation for a straight line, y=mx+b, the slope is the quantity represented by m that is multiplied on the x, and b is the y-intercept, i.e., the point where the line crosses the vertical y-axis.
To put the equation 5x + 2y = 3 in slope-intercept form, you need to rearrange the equation to have the form y = mx + b, where m is the slope and b is the y-intercept.
To do this, you can start by isolating the y term on one side of the equation:
5x + 2y = 3
2y = -5x + 3
y = (-5/2)x + (3/2)
In this configuration, the line's slope is -5/2, and its y-intercept is 3/2. Therefore, the equation of the line in slope-intercept form is y = (-5/2)x + (3/2).

Choose variables and constants to create new mathematical sentences to justify

Answer:
It is not possible to make both sides of the mathematical equation 2 ≠ 3 equal by using the Properties of Equality. This is because the equation is already in reduced form and there is no way to simplify it further.
If we try to apply the Properties of Equality to this equation, we can see that it is not possible to make both sides equal. For example, if we try to add or subtract a constant or variable to both sides, the result will not be modified. If we try to multiply or divide both sides by a constant or variable, the result will also not be modified.
Therefore, it is not possible to make both sides of the mathematical equation 2 ≠ 3 equal using the Properties of Equality.

Determine the largest integer value of x in the solution of the following inequality.

Answer: -6
Step-by-step explanation: To determine the largest integer value of x in the solution of the inequality 2x+6<-4, we first need to isolate x on one side of the inequality. We can do this by subtracting 6 from both sides of the inequality, which gives us 2x<-10. Next, we can divide both sides of the inequality by 2, which gives us x<-5. Since the inequality has a strict inequality symbol, we can conclude that the largest integer value of x that satisfies the inequality is -6.

Since we require the number of milliters of acetaminophen required for a 55 pound child.
Since n = L/m
L = mn
Given that
m = 55 pounds = 55 lb and n = 0.2 ml/lbSo, susbstituting the values of the variables into the equation, we have
L = mn
= 55 lb × 0.2 ml/lb
= 11 ml
So, the number of milliliters is 11 ml
